Restoring the database back to an earlier point in time, also known as [Point in Time Restore](/azure/azure-sql/database/recovery-using-backups#point-in-time-restore), is an operation frequently used when a mistake occurs and users need to quickly revert the state of the database back to an earlier point in time. When uploading the generated digests to Azure Storage or Azure Confidential Ledger, the *create time* of the database is captured that these digests map to. Every time the database is restored, it's tagged with a new *create time* and this technique allows us to store the digests across different "incarnations" of the database. For SQL Server, the *create time* is the current UTC time when the digest upload is enabled for the first time. Ledger preserves the information regarding when a restore operation occurred, allowing the verification process to use all the relevant digests across the various incarnations of the database. Additionally, users can inspect all digests for different create times to identify when the database was restored and how far back it was restored to. Since this data is written in immutable storage, this information is protected as well.
